REVOLUBLE SHOW-CA8 E.

SPECIFICATION forming part of Letters Patent No. 726,900, dated May 5,1903. 7

Application filed January 9,1903. Serial No. 138,384. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES GANTERT, a citizen of the United States,residing at Rock Island, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements in RevolubleShow- Cases, of which the following is a specification, reference beingbad therein to the accompanying drawings.

My invention relates to revoluble showcases; and it is my object toprovide a showcase of this type with a series of hinged doors orclosures having spring-latches which are automatically operated byrevolving the case to unlock each door as it arrives at a givenpoint-as, for example, when the several doors reach a point facing theoperator behind the counter they become unlocked.

I have shown my invention as applied to an upright revolving case forexhibiting plug tobacco having a division in the middle; but I do notconfine myself to this type of revolving show-case, as it is evident myinvention is adapted to other types of revolving cases.

In the accompanying drawings, forming a part of this specification,Figure 1 is a front elevation of the revolving show-case mounted upon apedestal. Fig. 2 is a central vertical section of said case and itspedestal, showing the locking mechanism and means for operating thesame. Fig. 3 is a top plan view of the top of the pedestal, and Fig.-lis a bottom plan view of the show-case.

Referring more particularly to the drawings, A denotes an uprightrcvoluble showcase, and ll a pedestal upon which said case is mounted.The case proper is composed of of a top piece A, bottom piece A", andpartition A framed in with four uprights or risers A, forming anoctagonal frame with an upper and lower compartment, which areseparatcdby the partition A.

A denotes eight glass doors the frames .of which are hinged to therisers A and provided with catches (a The bottom A is pro vided with acentral bearing a, whi'cli'rcgisters with a journal projecting from thetop of the pedestal. It is also provided with four friction-rollers a,which ride upon a track, hereinafter mentioned. C denotes four armspivoted midwayof their-length to bearings c,

friction-wheels secured at one end of said arms 0, the other ends ofsaid arms being pivoted to four vertical plungers D, which secured tosaid bottom piece. 0 denotes four bearing a in the-botton'l of theshow-case in which it revolves.

B denotes a circular track fastened to the top of the pedestal on whichthe frictiopwheels a bear.

B denotes a shoe or short raised track with beveled ends mountfed to thetop of the podestal outside of the circular track in the path of thefriction-wheels c. Said wheels c in their normal position strike thetrack BF and ride over it, as hereinafter mentioned.

The plungers D are preferably. divided.

about midway of their length and their ends united by turnbuckles D.Theupper ends of each plunger are threaded andprovided with threadedcollars, which are thereby adv j ustable vertically.

E denotes metal plates fastened to the risers about midway of theirlength, provided with pivoted latches e, which engage catches-a.

Said catches have projecting ends e, which are perforated to admit thepassage of the upper ends of the plungers D. I

e denotes coiled springs securedto plates E and fastened to projectingends of said latches. The tension of said springs is such that theplunger-rods are drawn up to their normal place, andin this position ofthe plnn: gers the glass doors of the revolving case are held locked.This position of the plungerrods also holds upward the endof. the arms0, to which itis attached, and thus holds down the opposite ends ofsaidarms carrying the friction-wheels 0, so that as the showcase isrevolved said wheels will contactwith and ride over the shoe B Theshow-case being: mounted upon the pedestal and the several parts beingadjusted as described, they will operate as follows to unlock each oneof the glass doors as they arrive in turn oppositethe point desired. Thepedestal is arranged with the shoe- B at the iii point desired where thedoors are to be unlocked. As the case is revolved the nearest end willthusbe raised from engagement with the catch a. Thus each door in turnwill be automatically unlocked as it reaches the position mentioned.

Having thus described my invention, what I claim, and desire to secureby Letters Pat-' cut, is

1. A rotary showcase having a series of hinged doors arranged withspring-latches a series of plungers connected to said latches tation tounlock said latches at and means for operating said plungers in roagiven point at each revolution of said case.

2. In a rotary show-case the combination ofv thehinged doors, latchesfor said doors, plunger-rods connected to said latches, springs foractuating said plunger-rods in one direction, pivoted arms connected tosaid plunger-rods for actuating the same in the opposite direction, andmeans for actuating said arms in rotation at a given point to unlocksai'd latches. 3. In a revolving show-case the combination of the hingeddoors, the latches, the plunger-rods, the springs attached to saidlatches and plunger-rods, the pivoted arms attached to the bottom of theshow-case having one end connected to the plunger-rods and their freeends projecting below the case and a stationary shoe arranged exteriorof the showcase and in the path of the free ends of said pivoted armsand adapted to rock the arms in rotation at a given point.

In testimony whereof I affix my signatn re in presence of two witnesses.
